Evolutionists constantly try to disavow the logical link between Darwinism and social Darwinism, but no matter how they try to divorce themselves from it, even Darwin himself understood that this logical conclusion followed because humans are part of the natural order. Below are a couple of quotes from Darwin, alongside one each by Nietzsche and Hitler. Chilling, isn’t it? While it is often a cheap trick to compare one’s ideological opponents to Hitler, in this case, made well in the recent book From Darwin to Hitler, the shoe fits perfectly.
I could show fight on natural selection having done and doing more for the progress of civilization than you seem inclined to admit. Remember what risk the nations of Europe ran, not so many centuries ago, of being overwhelmed by the Turk, and how ridiculous such an idea now is! The more civilized so-called Caucasian races have beaten the Turkish hollow in the struggle for existence. Looking to the world at no very distant date, what an endless number of the lower races will have been eliminated by the higher civilized races throughout the world.
– Charles Darwin, in a letter to William Graham dated July 3, 1881
At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate and replace throughout the world the savage races.
– Charles Darwin, from The Descent of Man
The biblical prohibition “Thou shalt not kill” is a piece of naivte compared with the seriousness of Life’s own “Thou shalt not” issued to decadence: “Thou shalt not procreate!” “Life itself recognizes no solidarity, no “equal right,” between the healthy and the degenerate parts of an organism.” Sympathy for the decadents, equal rights for the ill-constituted – that would be the profoundest immorality, that would be anti-nature itself as morality!
A stronger race will supplant the weaker, since the drive for life in its final form will decimate every ridiculous fetter of the so-called “humaneness” of individuals, in order to make place for the true “humaneness of nature,” which destroys the weak to make place for the strong.
Of course, it could be argued that these are taken out of context, but I just omitted the context for the sake of brevity. If you want context, you can read the CT article Darwin’s Graveyards, or Weikart’s book From Darwin to Hitler.
